That's one of the coolest "features" of Bluetooth LE: Apple has decided that the risks to battery life and overall system integrity are low enough with BLE that they've left it quite wide open from an app-developer perspective. There's even an officially-supported background mode.

It remains to be seen exactly how far they are willing to go with unregistered protocols and custom hardware, but this type of "electronic leash" is an officially blessed protocol, so there should be no issues with their app.

Oh wow! I stand corrected, very useful to know. Looks like these folks are even smarter than I thought.

Still hope they tune up the design, though. Even beyond aesthetics, the usability leaves a lot to be desired.
